Transparent window makes smart cards more secure

If a smart card chip fails, an inspector – perhaps at a border or in a bank - must rely upon the physical security features within a card to authenticate the document and its user.

A new security concept for smart cards was recognised at the Cartes trade show, called ID-One Sky. It is a novel kind of physical security feature stemming from a collaboration between Oberthur Technologies, Graphic Security Systems Corporation and Alain Boucar, Chief Superintendent of the Belgian Federal Police.

An ID-One Sky card is made from polycarbonate and includes a transparent window which is a decoder for invisible markings present on the photo of another card. Two ID-One Sky cards authenticate each other by laying the transparent window of one over the cardholder photo of the other. Hidden data are then revealed and any tampering with the photo is immediately detected. This means a level 2 invisible security feature can be directly verified in the field without any specific or complex tool.

Hidden Indicia, a patented Scrambled Indicia technology developed by Graphic Security Systems Corporation, allows invisible data to be integrated into a photo. It is already used on several identity documents such as the new Belgium electronic passport manufactured by Oberthur Technologies.

Integration of a decoding transparent window in a polycarbonate smart card body requires the combined mastery of several technologies unique to fiduciary printers and smart card manufacturers.

"Security of a document is closely related to the ability of the first line to control it. Oberthur Technologies has a good grasp of this issue and ID-One Sky is the first identity document which allows us to integrate a second line dimension at the time of verification," says Alain Boucar, Chief Superintendent of the Belgian federal police.
